 These twin stones show that Gag died as relatively young as he is not mentioned on them.Estrid is the same person as the Estrid who is mentioned on a number of runestones in Täby and other locations (Hargs bro runic inscriptions and Uppland Rune Inscriptions 101, 143 and 147).This Estrid was the maternal ancestor of a great clan called the Jarlabanke clan, and she was the maternal grandmother of the powerful Jarlabanke who claimed to own all of Täby.
